Glastonbury effect?

Sir, – If Una Mullally thinks Glastonbury is such a fine example of good crowd behaviour (“Croker debacle down to disrespect for outdoor spaces”, Opinion & Analysis, July 7th), how come it needs a force of 800 people working for six weeks to clean up after it (“What’s hot, what’s not”, Magazine, July 5th)? – Yours, etc,
